SHAFT-HANGER..

SPECIFICATION forming part of Letters Patent No. l780,129, dated January1'?, 1905.

Application filed June 8, 1904. Serial No. 211,579.

To all whom, t may concern.'

Be it known that I, IVINFmLD S. Roenizs, a citizen of the United States,residing at Bantam, in the county of Litchfield and State ofConnecticut, have invented a new and useful Shaft-Hanger, of which thefollowing is a specification.

This invention relates to a shaft-hanger for supporting overheadshafting.

The object of this invention is to provide a strong, simple, andefiicient shaft -hanger which can be applied at an intermediate point onaline of shafting without removing the pulleys or other fixtures carriedby the shafting.

`To this end this invention consists of the shaft-hanger as an articleof manufacture and of the combinations of parts therein, as hereinafterdescribed, and more particularly point- 'ed out in the claims at the endof this specilication.

In the accompanying drawings, Figure 1 is a perspective view of ashaft-hanger constructed according to this invention, and Fig. 2 is aperspective view of parts thereof.

The shaft-hanger lconstructed according to this invention is a built-upstructure comprising parts so combined and fastened together that theycan be applied at any place upon a shaft after the shaft is already inposition;

The construction which I have illustrated herein as one embodiment of myinvention comprises two side brackets and a bottom plate. The sidebrackets are fastened together by transverse bolts, and the bottom plateis fastened in place on the lower ends of the four corner posts Ior armsby means ofV tap-bolts. The side brackets are provided withinwardlyfacing ledges, and the center screws which support the box orbearing are supported by thesle ledges and by the bottom plate,respective y.

Referring to the accompanying drawings and in detail, a shaft-hangerconstructed according to this invention, as herein illustrated,comprises side brackets B, each of which has two downwardly-extendingposts or cornerpieces l0. At their upper ends the side brackets B areprovided with ceiling-bolts having perforations 11.

Extending in from each of the side brackets B is a ledge l2. The ledgesl2 abut against each other to form a shelf or support and held in placein a socket, one-half of which is bored out. In each of the ledges l2 isa nut l5.

The side brackets B are fastened together by means of nuts threaded ontothe transverse bolts 13, and the fastening of the side brackets alsoholds the nutl in place in its socket.

Bolted onto the lower ends of the corner pieces or arms 10, by means oftap-bolts 14, is a bottom plate I). The bottom plate serves to stiffenand strengthen the construction, and in connection with the transversebolts 13 the bottom plate fastens the side brackets to form acomparatively stiff and rigid structure. The bottom screw S is threadedinto the bottom plate I), and the center screws S and T cooperate tohold the bearing-box R, which may be of any of the ordinary or approvedconstructions.

In the use of the completed shaft-hanger it will be seen that the hangermay be taken apart so that it can be put in place at any point in thelength of a shaft even after the shaft is already mounted in position.

In thc drawings I have shown the bearingbox, which is supported in thehanger-bracket, as formed in one integral piece or ring, and in order toapply this form of construction to intermediate points on a shaft it isnecessary that the bearing-rings should first be threaded onto the shaftapproximately in the desired positions before the shaft is put up. I donot wish, however, to be limited to the use of the particular ringbearing-box that I have illustrated, as it is obvious that differentforms of bearing-boxes may be used in connection with my hanger-bracket.

I am aware that changes may be made in the proportions of the parts bythose who are skilled in the art without departing from the scope of myinvention as expressed in the claims. I do not wish, therefore, to belimited to the particular details of construction which I have hereinshown and described; but

What I do claim, and desire to secure by Letters Patent of the UnitedStates, is-

l. As an article of manufacture, a shafthanger comprising two brackets,each having an in wardly-acing ledge, said ledges abutting to form asupport, and each bracket having two downwardly-extending arms,transverse bolts fastening the brackets together, a bottom plateconnecting the lower ends of the arms, bolts fastening the bottom platein place, a center screw supported by the ledges, and a center screwtapped into the bottom plate, said center screws coperating to support abearing box or ring.

2. As an article of manufacture, a shafthanger comprising two brackets,each having an inwardly-facing ledge, a nut fastened in place in asocket between said ledges, and a center screw threaded into said nutand coperating with a bottom center screw to support a bearing or box.
